If, after nearly being done in at the conclusion of Tombstone Courage, newly elected Cochise County, Ariz., sheriff Joanna Brady thought she deserved a calm spell, she had another think coming. The plucky widow, whose sheriff husband was slain on duty, reluctantly leaves her 13-year-old daughter and comfortable hometown of Bisbee for Tucson, where she enrolls in a sorely needed law-enforcement course. The big city is besieged by a number of brutal domestic-violence crimes, which turn out to be the work of an opportunistic serial killer. Joanna finds herself drawn into the case of one falsely accused suspect even as she hits the books and deflects verbal attacks from her neanderthal instructor.
